**Magn Tek** · Hall Switches · SOT-23

MT8382ET from Magn Tek, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Supply pin for the operating range of 3.8 V to 60 V, with -20 V reverse supply protection stated in the datasheet (abs. max VCC 65 V). |
| 2 | OUT | output | Open-collector output with a 40 mA maximum continuous output current, 65 V maximum output voltage, 0.4 V max saturation at 15 mA, and output current limiting; an internal 10 kΩ pull-up resistor is also listed as a feature. |
| 3 | GND | power_in | Ground pin for the device. |

## CAD (KiCad official)

- Symbol: `MT8382ET`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `mt8382et-etched.step` / `mt8382et-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mt8382et.step` / `mt8382et.glb` are the bare package body.
